Trouble installing vBulletin on Subdomain

[JORDANVBUSER]

Hi. I am attempting to install a copy of vBulletin 4.2.2 Patch Level 4 on a subdomain. My primary domain is www.televisionspeaks.com which hosts my Wordpress blog. From there, I set up a subdomain with HostGator as forum.televisionspeaks.com. I did the proper install by editing the config.php folder and then, using FileZilla, uploading all of the upload files to a 'forum' folder (public_html/forum).

At this point, I've tried going to forum.televisionspeaks.com/install/install.php, televisionspeaks.com/forum/install/install.php and several other variations. I'm a little confused if it's the URL I'm having trouble with or something more substantial.

Thus, I have checked out at least 20 threads across vBulletin by now concerning this issue and can't find a resolution... yet, which is why I'm hoping someone here would be able to help me out. I did look for the .htaccess file and even by turning on hidden files on my Mac I wasn't able to find it in the folder I downloaded from vB. There is a .htaccess folder under public_html/.htaccess, which didn't seem to contain anything specific to vB and only seemingly had Wordpress data inside it (?) so I'm not sure what to make of that. Many sources claimed that the vB folder should contain .htaccess but I still can't find it.

I'm relatively new to vBulletin, so I apologize if this is a lot simpler than I've made it out to be. I would appreciate any help with this issue! Thanks for reading!
